Rolling bearings are rolling bearings work under the friction. Rolling bearings easy to use and maintain, reliable, good starting performance, higher carrying capacity at moderate speeds. Compared with the sliding bearing, radial bearing large radial size, vibration capacity is poor, high-speed low-life, large sound. Rolling bearings in the radial bearing (mainly to bear radial force) usually by the inner ring, outer ring, rolling element and the rolling element cage 4 parts. The inner ring is tightly fitted on the journal and rotates with the shaft, and the outer ring is installed in the bearing seat hole. A raceway is formed on the inner periphery of the inner and outer rings. When the relative rotation of the inner and outer rings, rolling the inner and outer ring raceway rolling, they are separated by the cage to avoid friction with each other. Thrust bearing sub-tight ring and the two parts live. Tight ring and sleeve tight, live ring bearing in the bearing seat. Rings and rolling elements are usually made of high strength, good wear resistance of the rolling bearing steel, hardened surface hardness should reach HRC60 ~ 65. Cage made of multi-purpose stamping of soft steel, copper alloy can also be used cloth or plastic bakelite and other manufacturing.
Such bearings are used for mining transportation machinery, mining materials must have coal safety certificate, nylon cage bearings in line with national coal safety standards. Effectively prevent the rolling bearing caused by static electricity. Solid nylon cage is characterized by a good combination of strength and flexibility, nylon with lubricated steel surface has good sliding performance, while rolling contact with the cage surface is smooth, resulting in little friction, so the bearing heat and Wear is very low. Low-density material means that the cage inertia is very small. The nylon retainer has excellent operating characteristics in the absence of lubricant, allowing the bearing to continue operating for a period of time, which does not result in fast locking and further damage.
